Intensity of supervision and outcome for preschool aged children receiving early and intensive behavioral interventions: A preliminary study
Section snippets
Participants
Participants were clients of UK Young Autism Project (UK YAP) which is the British replication site for the UCLA International Multi-site Young Autism Project, directed by Drs. O. Ivar Lovaas, University of California, Los Angeles and Tristram Smith, University of Rochester, New York. All children residing within specified locations, who joined UK YAP between Autumn of 1998 and Spring 2005 were included in the study if they met all of the following criteria: (a) a diagnosis of autism according
Results
Table 1 has intake and follow-up scores (including standard deviation and range) on chronological age, IQ, visual spatial IQ, Reynell comprehension, Reynell expressive language, and Vineland Adaptive Behavior Scales. As can be seen in Table 1, mean intake age for the 20 participants completing the study was 34.9 months (S.D. = 5.7). Follow-up assessment was conducted 14 months (S.D. = 6.1) after treatment began. Mean intake IQ was 54 (S.D. = 15.1); mean follow-up IQ was 71 (S.D. = 22.1).
Mean cumulative
Discussion
This study asked whether intensity of supervision is associated with outcome in preschool aged children with autism who received early and intensive behavioral intervention. Intensity of supervision ranged from 2.9 to 7.8 h per month per child. A significant correlation was noted between intensity of supervision and change in IQ scores between intake and follow-up. Thus, intensity of supervision was reliably associated with amount of IQ score change between intake and follow-up. Moreover, the

Competency drivers to support implementation of early intensive behavioral intervention in large-scale community-based services: Perspectives of caseworkers and organization representatives
2023, Evaluation and Program PlanningCitation Excerpt :Långh et al. (2017) noted that supervision helps improve the knowledge of caseworkers who apply EIBI in contexts of community-based services. Some results suggest that supervision is associated with EIBI quality (Eikeseth et al., 2009; Reichow & Wolery, 2009). However, further research on the subject is needed, notably in contexts of services offered by public organizations, where resources to do so are often limited.
Assessing competencies in applied behavior analysis for tutors working with children with autism in a school-based setting
2015, Research in Autism Spectrum DisordersCitation Excerpt :Perry and Freeman (1996) suggest that individual outcome is a result of child, family and intervention variables. For example, child age, IQ, adaptive scores and severity of autism (Perry et al., 2011) and intensity of supervision (Eikeseth, Hayward, Gale, Gitlesen, & Eldevik, 2009), have all been shown to be predictive of outcomes. Intervention variables include both quantity and quality.

2015, Behavior TherapyCitation Excerpt :These procedures are usually incorporated into the design of clinical trials to help ensure internal validity and typically include (a) procedures for promoting acquisition of specific clinical skills (i.e., treatment manuals, methods for training practitioners), (b) procedures for maintaining treatment integrity (i.e., methods for supervising practitioners), and (c) tools for assessing treatment integrity. Unfortunately, EBI techniques for ASD are not always well documented in treatment manuals (Smith, Eikeseth, Sallows, & Graupner, 2009), procedures for practitioner training and supervision are not always clearly detailed (e.g., Eikeseth, Hayward, Gale, Gitlesen, & Eldevik, 2009), and many EBIs for ASD do not have tools to monitor treatment integrity (cf. Hume et al., 2011). As these elements are fundamental to implementation research, a priority for the field is to develop tools and procedures required to support practitioner skill acquisition and implementation in their clinical work.
